The Coalition for Wilderness, initially proposed by Addison, represented five groups in speaking for wilderness parks in Ontario: Algonquin Wildlands League, Canadian Nature Federation, Federation of Ontario Naturalists, National and Provincial Parks Association of Canada, and Sierra Club Ontario Chapter.

Correspondence, reports, and minutes regarding logging and forest conservation in Quetico Provincial Park collected by Dr. Harold S. Braun of Lakehead University.

The Save Quetico Committee was formed mostly of Thunder Bay residents, to advocate for an end to logging in Quetico Park. The initial push was in 1970 (prompted by actions taken by the Algonquin Wildlands League), but the issue persists through the 1990s.

The position paper of the Save Quetico Committee, written by Addison, significantly influenced the first Quetico Master Plan.
